My eyeballs have decided, as of about 2 years ago and with increasing recalcitrance, that they are on strike as far as bothering to reshape the lens so as to refocus depending on the distance of whatever I’m trying to look at.
The nearby objects are still in focus if I put my grubby hands on the frame of my glasses and bend them so as to bring everything into focus.
I can also just remove the glasses, which are for nearsightedness, and see nearby objects in damn good focus. Just can’t see anything that’s not nearby.
LASIK, as I understand it, will do unto my eyeballs what the spectacles compensate for. I would not have to wear glasses. But it isn’t going to do diddly for me w/regards to being able to shift focus to things close to me, right? So let’s not fish for that red herring.
What I want is a pair of glasses that have two lenses per eyeball, and a little thumbwheel in the earpiece of each that I can use to change the distance between the two lenses so as to focus, if my eyeballs aren’t doing it on their own. I know it would work, I am absolutely positively certain of it, I’ve used enough optical equipment that relies on two lenses per eye and a focus knob to be that sure of it, the only question is can they make such a device and have it not be cumbersome (yet), and will they bother marketing it fi they can?
That’s really what I want: focus control. I don’t mind wearing glasses, worn them since I was in 4th grade, and now I want Glasses II.
It takes distance between optical elements to accomplish changing the focal length of the assembly, which is what you want to do. None of the devices you have seen before had an optical path a couple inches wide but were only 1/4" from front to back, which is what we find useable on eyeglasses.
I’d like to see this too.
In the meantime, limited accomodation or presbyopia are what bifocals and trifocals are for. Just this week I had “computer spex” made, which are halfway between my distance and reading prescriptions. What a pain. My damn neck is getting into the act, too…
Feh. I’d just like them to make my prescription “readers” work as good as the Walgreens version. After two adjustments, mine suck. I keep them in my purse and only use them for menus and other “away from home” reading (and because the frames are so damn cute). My $10 cheaters are way better for computer and book reading.
I had bifocals for a while (the lineless kind just didn’t work for me.) Then I went to trifocals. Very soon, I won’t need 'em at all. I grew cataracts, and two weeks ago, Dr. Woschitz did microsurgery on my right eye. He took out the human lens in pieces, then he put in a Restor® bifocal lens. Tomorrow, I get the other eye done.
My right eye is just a little blurry at distance. Dr. Woschitz says the close part rarely comes on until both implants are in. So, I should be “looking” good in another week or two. I may have to take a break from the SDMB while my new eyes learn to work.
